Fixed 64-bit integer truncation issues in shader translator.
This is an incompatible API change, but one which is necessary in
order to improve correctness of the code. The API version in
ShaderLang.h is updated and, unfortunately, the define renamed to
something less ambiguous due to conflicts on some Android buildbots.
Temporary patches in Chromium and WebKit will be landed separately to
support this upgrade.

Preparation of hooking up the new preprocessor.
- Added custom Diagnostics class. Routed all info-log messages via this new class.
- Added custom DirectiveHandler class. Moved directive-handling code to this class and routed the old path.
- Deleted lexer_glue because it is not needed anymore. The new preprocessor is almost ready!
- Killed a bunch of dead code related to PragmaTable.

Unroll for-loop if sampler array uses loop index as its index.
If inside a for-loop, sampler array index is the loop index, Mac cg compiler will crash. This CL unroll the loop in such situation. The behavior is:
1) If the for-loop index is a float, we reject the shader.
2) If it is an integer, we unroll the for-loop.
Things that should be done in the future are:
1) Add line number macros.
2) Add a limit to unroll iteration count.

Implemented validation for loop and indexing limitations specified by GLSL ES spec 1.0 Appendix A Section 4 and 5.
A couple of things to note:
- This CL only validates the "form" of loop and indexing. It does not detect number-of-iterations or out-of-bound access. This will require more involved analysis/heuristics.
- I haved combined SH_VALIDATE_CONTROL_FLOW and SH_VALIDATE_INDEXING into one flag - SH_VALIDATE_LOOP_INDEXING. Validating both together is much easier.
